What is a single phase inverter and who needs one?

A single phase inverter converts DC power from solar panels or a battery into 230V AC power for standard household circuits. Most South African homes, small businesses, and farms run on a single phase supply. If your property has one electricity meter and no three-phase equipment, a single phase inverter is the correct choice. Three-phase properties such as farms with large motors and commercial buildings need a 3-phase inverter instead.

What size single phase inverter do I need for my home?

A 5kW inverter suits most South African homes with standard lighting, a fridge, TV, and small appliances. An 8kW or 10kW inverter suits larger homes with a pool pump, underfloor heating, or air conditioners. A 12kW or 16kW model suits high-consumption homes or small businesses with multiple heavy loads running simultaneously. SP-Energy can size your system based on your monthly electricity bill and peak load requirements.

What is the difference between a hybrid and an off-grid single phase inverter?

A hybrid inverter connects to both the Eskom grid and a battery bank. It uses solar power first, stores excess in the battery, and draws from the grid only when solar and battery are insufficient. An off-grid inverter has no grid connection and runs entirely from solar and battery. Hybrid models are better for urban homes. Off-grid models suit farms and remote properties where grid connection is impractical or unavailable.

Can a single phase inverter protect my home during loadshedding?

Yes. A hybrid single phase inverter with a correctly sized lithium battery switches to battery power automatically when the grid goes down. The switchover takes milliseconds and most connected appliances do not notice the transition. The battery recharges from solar during the day, so the system continues to protect your home through repeated outages without drawing from the grid.
